I'm told GWT is very nice to develop in, but it generates rather large javascript files, so probably not something to use if you just want to add some interactivity to your web pages. If you already know java don't want to learn javascript, and you want to develop a significant application that interacts tightly with HTML, this is a great way to go. I played around with YUI a bit - I liked it. Kind of a large library again, so probably not something to use if you just want to add interactivity to your web pages, but their source code is nice and well-documented. JQuery (jquery.com) is quite nice and has a very small footprint. It's well documented and has a good community around it. If you just want to add some interactivity to your web pages, this is my favorite solution. Flex is great to develop in, but its integration with HTML is really poor. They have a rich-text control, but its support of HTML is limited to a few basic tags. There are claims that you can embed full HTML in an iframe, but the solution isn't officially supported, doesn't work on Safari, and if you want to pop up a dialog over the iframe you have to hide the iframe first. Adobe says they're going to be coming out with Apollo soon, which will allow you to develop disconnected apps and is supposed to have better HTML integration - we'll see. If you can figure out how to avoid displaying HTML in your app (e.g., by displaying the HTML in a different frame altogether), then Flex is very nice. Flex functions can call Javascript and vice-versa. Even though it's $$$, I think it's worth the money. Regardless, get yourself a good console logger/debugger/inspector. I use FireBug for javascript and xpanel for Flex. -dallan
_____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jay Askren Sent: Friday, January 05, 2007 7:51 AM To: LDS Open Source Software Subject: [Ldsoss] Laslo vs Flex vs GWT vs ? I know there are a lot of web developers out there. I'm looking into the various AJAX frameworks out there and was wondering if someone could give me a run down of the advantages/disadvantages of the various frameworks. I know of Laslo, Flex, and GWT. I believe these are all major players in the AJAX world. Are there other major players I'm missing? Is there any agreement over which is better than another? Thanks. Jay
